No, as of 2026, Lisbon's iconic Tram 28 is no longer cash-only, although cash is still accepted if you buy a ticket directly from the driver. However, buying a ticket on board with cash is the most expensive option, costing €3.30 for a single trip. In 2026, most tourists use the Navegante (formerly Viva Viagem) card, which can be loaded with "Zapping" credit to bring the cost down to about €1.70 per journey. Furthermore, the trams have been updated with contactless payment terminals that allow you to tap your Visa, Mastercard, or mobile wallet (Apple/Google Pay) directly at the validator near the door. For those planning to do extensive sightseeing, the 24-hour unlimited public transport ticket (€7.25) or the Lisboa Card are the most efficient ways to pay, as they cover all trams, buses, and the Metro. While you can still pay with cash, it is highly discouraged during 2026 peak hours because it slows down the boarding process for one of the city's most congested transit lines.
